Why Do Sedans Cause Motion Sickness While SUVs Don't?

[AvaMarie]

SUVs are characterized by their spacious interiors, which prevent passengers from feeling cramped, good air circulation, high ground clearance, and large windows offering broad visibility. Most SUVs have stiffer suspensions compared to sedans, eliminating the soft, bouncy sensation typical of sedans. Additionally, SUVs generally have poorer acceleration performance due to their larger size and higher weight, leading to a more stable driving style. These factors significantly reduce the likelihood of motion sickness. Below is an extended explanation: The causes of motion sickness: Motion sickness is primarily related to the vestibular system. The vestibular system in the inner ear is the main system responsible for maintaining the body's balance. When the two vestibular systems receive inconsistent signals, it disrupts the balance system, leading to dizziness. Factors such as confined car spaces, poor air circulation, limited visibility, overly soft suspensions, unpleasant odors or fuel smells, sudden acceleration, and abrupt braking can easily trigger motion sickness.
